TO ALL WHOM I'l MAY CONCERN:

Be it known that I, BUItDE'r C. HOUSE, of Morris, in the county of Grundy, in the State of Illinois, have invented a new and useful Improvement in Ploughs; and I do hereby declare that the following is a full, clear, and direct description of the same, reference being had to the accompanying drawings, forming part of this specification.

Figure I is a side view.

Figure 2, a top view of a round rotary steel cutter.

Figure 3, a transverse section, ns indicated by lines a: y Iin figs. I and 2.

Like letters in the different figures of the drawings indicate like parts.

The nature of my invention consists in attaching to the heel of the`shear-bar a round rotary steel cutter of any desired size by means of a socket cast or wrought into the heel ofthe shear-bar perpendicnlarly, so that its centre shall be inside of the inner surface of the shear-bar, in which socket a perpcndicularspindle or axle, to the lower end of which is irmlyrattaehed the revolving cutter, is made torevolve by the forward motion of the plough, it being held in its place by means of a nut countersunk in the top of the socket: The cutter revolves horizontally, and the lower surface is even with the lower edge of the shear-bar, the shear-bar being gained up the thickness of the cutter for that purpose. Thus, when in motion the cutter revolves and separates a portion of the uuturned sod from the soil, and in so doing lessens very materially the friction'on the land-side of the plough, thus enabling amould-board of any given width to turn, especially in sod land, a much wider furrow and with less propelling power than any of the ploughs now in use. i

To enable others skilled in the art to make and use my invention, Iwillv proceed to describe its construction and operation.

A represents the revolving cutter, which I make of 71 plough-steel, forging and grinding it to an edge on the outer edge. Itis swaged up from the bottom in the centre about the thicknessof the plate, and the sise of and to correspond with the outside circumference of the socket standard, leaving a cavity the same thickness beneath. B represents the socket standard, which is made by turning the heel of the shear-bar inwardly and around, so that the centre of the socket and of motion shall come inside of the inner surface of the shear-bar, thus rendering it impossible but that the cutter shall revolve when the plough is in motion. It is countersunk at top and bottom to admit the nut G on top, and correspond with the bevelled shoulder beneath. C represents the spindle or axle attached to cutter, the lower end D havinga screw cut on it up to the shoulder. It is then screwed firmly into the cutter standing perpendicular to its upper surface, the cavity on the under side of which is filled by a thin washer of iron, over. which the end of the screw tenen is riveted so as toattach the spindle firmly to the cutter and leaveasmooth, even surface ou the lower side of the wheel. The spindle is bevelled up from the shoulder, the socket being bevelled to fit when it is inserted in the socket. The upper end of the spindle E has also a screw cut, and rea-ches to thc upper surface of the shear-bar or socket. Over this is screwed the nut G,

which is screwed down into the eountersunk part of the socket so a's to come even with or below the surface ofthe shear-bar, thus holding the cutter to its place. The lower edge of the shear-bar is notched or gained up so as to let the lower surface of the cutter come even with the lower. edge of the shear-bar. When the plough is in motion the cutter revolves, and thereby avoids friction in cutting under the unturned rod. .It is made to perform its function by the lateral force necessary to turn the furrow, instead of the direct force used in drawing the plough. The lateral force of turning thc furrow being relieved or in ameasure couuteracted by the cutter, relieves in so far the friction on the land-side of the shear-bar, thus enabling any given propelling force to turn a third wider furrow than the ploughs new in use. lhe size of the cutter will of course vary according to the size of the plough. It should cut under the sod one-third the width of the furrow.

What I claim as my invention, and desire to secure by Letters Patent, is-

The rotary land-side cutter, in.combination with the shear-bar at its point B, and arranged in the marmer and for the purpose above set forth.
